OEM Connected Extension Springs Service
The connected round shackle extension spring is formed by bending and twisting the spring coil at the end of the spring to the center, and high stress is formed at the bending and twisting place. It is suitable for springs with a large winding ratio and a small load. Long arm shackles are mostly used in springs with smaller wire diameters. All the hooks and loops formed by bending process generate relatively large stress concentration at the bending of the steel wire. Therefore, the end structure of the hook and loop formed by bending processing is recommended to be applied to springs with a material diameter of less than 4mm. However, because this method is simple, it is sometimes used for springs with a material diameter of about 10mm, but the radius of the bending fillet should be as large as possible, and it should be smooth and free of scars.
- Size: wire diameter 0.08mm~8.0mm
- Material: 304, 302, 301, 316, 631, 65Mn, 70, 80, T8A, T9A, 60Si2Mn, 55CrSi, 50CrVA, beryllium copper, brass, red copper, phosphor bronze, high temperature resistance, corrosion resistance, memory alloy, etc.
- Surface treatment: blackening, zinc plating, nickel plating, shot peening, polishing, dacromet, anti-rust oil, electrolytic polishing, Teflon spraying, etc.
